This case study reports on the effect of Korean medicine on a catheter-associated urinary tract infection (CAUTI) caused by multidrug-resistant Pseudomonas aeruginosa. An 83-year-old man diagnosed with stroke had dysuria, and it was found that an indwelling urinary catheter led to CAUTI. From laboratory tests, we identified multidrug-resistant Pseudomonas aeruginosa and applied Korean medicine to him. After herbal medication with acupuncture and moxibustion, we studied a urinalysis and urine culture again for follow-up. We found meaningful improvement in bacteriuria and bacterial identification. This case suggests that Korean medicine could have a beneficial effect on urinary tract infections caused by multidrug-resistant Pseudomonas aeruginosa.

Dry wall using steel stud has the advantage of possibility to install various building, so it used to many buildings inside and outside of the country very rapidly. Though Light gauge steel framed housing offers many advantages to the consumer and the builder, the use of steel studs in wall system cause thermal problems such as thermal performance and pattern staing on walls. The present study has been conducted to observe effect of stud by the shape, and two kind of stud is made for this test to compare thermal performance. The test was conducted by setting those stud on the chamber and heating them. As the results of test and photograping by using TVS, there was temperature gap of each stud, and surface temperature of each section was appeared differently due to shape of stud delaying thermal bridge.

It is necessary to develop future-oriented and innovative energy technology in architecture area in order to handle the crisis about energy-environment problem. So this architecture area has been spurring the development of new technology for energy saving and alternative energy use. Double skin window system, an active covering to repond to the exterior change of the environment, is a skill that can reduce the indoor cooling and heating load and realize the environmental architecture. This study works out U-value of windows using the window-simulation program with the development and study of the double skin. And the effect of the double skin insulation on the effeciency rating has been analyzed, applying to the certification system of the building energy effeciency rating which has implemented.

The measures for energy saving in buildings have been tried because particularly the role of building division is very important for implementing national greenhouse gas reduction targets and Green growth. However there are many problems due to lack of relevant personnel to do this work. Furthermore it is expected that certification services will be increased by revitalizing the Building Energy Rating System and expanding the target of certification. Therefore Government must prepare for the expansion of the Building Energy Rating System by training experts with effort to supply low-energy building. This expert survey results are that 72% of the respondents answer that expansion of the certification authority is needed to prepare for increase in the certification and 87% answer that training experts is needed. In this study, we suggest the basic data for the introduction of obligation and expanding certification by analyzing the operating system and legal system of the Building Energy Rating System. Additionally, the operating and legal system of the Building Energy Rating System which is appropriate for our country will need to be built based on practices in developed countries to present way to expand the target of certification.

Enhancement of exterior's insulation performance like wall or window etc. is general way for building's energy efficient and thermal performance. But exterior's opening plan is important for minimizing the energy consumption and heat loss. In this paper, energy saving rate will be analyzed and compared considering the window area's rate in a apartment with Building Energy Rating System's evaluation tool. In the process of evaluation, energy saving rate is measured at each stage of the window area's rate from 20% to 60% every 10% term. As a result of this research, energy saving evaluation could not be measured exactly with existing evaluation tool. Accord this research, Building Energy Rating System's evaluation range is needed to be broaden for exact evaluation of energy saving rate.

Currently, Exterior wall's U-value about building envelope is 0.29~0.47W/㎡K(Central Region), but window's one is 3.3W/㎡K according to air gap of glazing, filling gas, coating and type of windows. The door's one is 1.6~5.5W/㎡ · K depending on material and configuration of door. As such, energy loss per unit of door is considerably larger like windows. The door for the recognition was relatively low because energy loss through the door is relatively small compared to window area. In this paper, thermal performance was analyzed through simulation targeting the door which has thermal break that can improve the insulation performance and doesn't have one.

Though steel stud house offers many advantages to the consumer and the builder, the use of steel studs in dry wall system causes thermal problems such as heat bridge or pattern staying on walls. The purpose of this study is to measure thermal performance of dry wall which uses steel stud transformed one by using measurement equipment to decrease heat bridge of steel stud and ensure heat performance. As results of test and photograping by using TVS, there was temperature gap of each stud and surface temperature of each section appeared differently due to shape of stud which delays thermal bridge. As a comparative performance test result, the performance of dry wall which uses steel stud transformed one has been improved compare with the dry wall using general steel stud.

Entering in the time of high oil price, seriousness of an energy effect sector has given a huge impact and the importance of energy is growing. Especially, building energy occupying 24% of total demand of energy is expected to be possible to reduce energy demand more than other section. To reduce the building energy consumption, this study analyzes function and thermal performance of Super window by heat experimental apparatus. Super window is a 2-track low-e glazing window for high insulation efficiency. By applying the results of this experiment to building energy efficience rating tool, this study compares energy efficiency rates depending on a region.-Jeju, South, Central. And it shows how much does Super window reduce Building energy consumption.

The parts of building which has the most influence on thermal load are skins, outer walls and windows. Among them, window is the worst weak point of building even if it has many advantage of solar radiation gain than other parts. The present time, many researches on various performance of window and many types of system-window are being made. This study evaluates thermal performance of tilt & sliding system window by simulation program Therm 5.2 and Window 5.2. After making a sample model improving it's thermal weak point, this study evaluates real thermal performace of system window. As a result, this study understands manufacture ability condition of domestic company and proposes a research plan of system window.
